I also think that with LEDs somewhat ,the CalMag needs increase ..
Mg is used for production of chlorophylls ,mainly .
Ca is used -as is - for " hardening" the cellular membranes and not only ..

Ca is suspected to have an idirect relation to elevated THC production ...
http://csalabs.com/marijuana-potency-the-role-of-stress-in-a-plants-life-cycle/

But ,one has to be very cautious with Ca .Very "dangerous" element .
Causes multiple lock-outs ( Fe , K , S , P ,Mo for example ...
Those elements easily react with Ca ions and produce unsoluble to water salts ..),
pH changes (increase pH rather drastically ) ,etc ..

Best organic source of CalMag ?

"Lithothamnium Calcareum "
http://www.agrimer.com/en/algues/3-red/15-lithothamnium-calcareum.html

search for " lithothamnium calcareum calmag granoule fertiliser " .(slow release organic fertiliser ).
Personally ,i use the one from DCM brand ,for almost a decade ,now.
Never had a Ca lock -out .


Cheers.

Best way to not have calcium or mag problems is to amend soil with dolomite lime or oyster shell.

Both will need some hundred years to completely dissolve ...
Let alone to be assimilated from a needy plant ..
Even if they are milled down to the finest powder ever ...
Not easily dissolving materials to water .
Way too much time needed .


Cheers.

What do you mean ? You don't need bottled nutrients to get nutrients to your plant...I completely moved away from anything in a bottle I use only natural and organic products , nothing dissolved in water. My plants don't have any deficiency or anything and I use LEDs and HID lighting. Dolomite lime is a well known and used organic product to prevent cal/mg problems in organic mediums you don't need to douse with salt based fertilizers to get the job done...there are other ways.

Did I mentioned anything about any bottled or mineral fertilisers ... ?

What it is

At an early stage the company decided that they would leave the Calcified
Seaweed in its original, natural state. Trials with milled material showed
it to be difficult to process and handle, the fine grains edging their way
into the bearings of both processing and farm machinery. However, around 5%
of the company's 30,000 tonne a year production is still sold in milled
form. Of the remainder, approximately half is sold in bulk and half in bags.
Calcified Seaweed is a species of a marine plant known as LITHOTHAMNIUM
CALCAREUM. It is found in deposits in Cornish coastal waters. Its structure
is like that of coral and it builds this structure from the minerals and
trace elements which abound in sea water. It is hard and porous and it
breaks down slowly and steadily when applied to the soil. It makes available
to the plant its own considerable range of minerals and trace elements and
also 'conditions' the soil. It helps release minerals and trace elements
from the soil, applied fertilizers and FYM to the plant. The effect is an
improved sward, enhanced palatability and better feed value of the grass,
and, as a result, improvements to the grazing livestock. Is a safe, reliable
and effective product used to good advantage for pasture improvement and for
all types of cattle for almost 30 years. It is sold in 25kg, 50kg and 500kg
bags (6% moisture) and bulk (about 17% moisture). The network of around 30
sales agents; though sales are still primarily to the livestock sector,
important markets have been opening up in arable areas. It is also an
important aid to organic farming.

I stay away from seaweed and ocean products cause in my experience they freaking smell so horrible they make your whole grow room smell bad and it starts to creep into your house.

No,I'm actually saying this
"dolomite lime wont dissolve ,even if it watered down with ordinary tap/mineral water " .

Inorganic chemistry .
I know that from 13-14 years old ...

Because dolomite can be dissolved by slightly acidic water, areas of dolomite are important as aquifers and contribute to karst terrain formation.
In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source.

http://en.wikipedia.org/wiki/Dolomite


All carbonates have some water solubility and dissolve readily in acidic water.

Not much Ca ,from dolomite stone,then.
Not enough to cover the increased growth rates and the demand of artificially grown plants.

Except if you water the plants with " Perrier " acid- water ..
